Are you a senior software engineer with a passion for building technology that drives sustainability and environmental impact? Do you want to use your software skills to support solutions that help organisations reduce carbon emissions, optimise energy systems, or accelerate the transition to a greener future? If so, this is an exciting opportunity to join a mission-driven tech organisation at the forefront of clean technology.

Our client, an innovative green-tech software company, is growing its engineering team in London and seeking a Senior Software Developer to help build and scale digital platforms that support sustainable outcomes. You'll work on products and services that empower businesses, communities and governments to monitor, analyse and improve environmental performance while driving operational efficiencies and climate goals.

As a Senior Software Developer, you will be responsible for designing, implementing and maintaining high-quality software across the stack. You'll work with a modern Microsoft-centric stack including C#, .NET 8+, ASP.NET, Entity Framework and .NET MAUI, and collaborate across backend and frontend development tasks. Your contributions will directly shape platforms used by customers seeking to address complex sustainability challenges - from carbon reporting and energy optimisation to real-time data analytics and integration with IoT systems.

You will participate fully in an Agile engineering process, working with product owners, designers and other developers to translate business and user needs into maintainable, scalable features. You'll write clean, well-tested code, implement APIs and services, and contribute to architecture discussions that directly influence product direction. You'll also support modern cloud-based deployment practices using Azure DevOps or similar CI/CD tooling, ensuring robust delivery pipelines and operational confidence.

We're looking for someone who not only brings strong technical skills and experience but also aligns with a purpose-led mission. You should be energised by the opportunity to apply your software craft toward environmental and social benefit, and thrive in a collaborative, agile environment where innovation and quality are valued.

This is a fantastic opportunity to be part of a forward-looking engineering team where your work supports meaningful change - helping organisations transition to cleaner, smarter, more sustainable operations.
